Hello All,
I'm new to the forum and am hoping someone can identify what's happened in my tank. Unfortunately, I think I'm beyond the emergency stage since 20 of my 23 fish have already died. I've had fish for decades and never had such a sudden death (from first sign of symptoms to death in two days). I have a 55 gallon tank, with Neon tetras, Red Eye Tetras, two plecos, white clouds, one angel and one orange glow fish. The tank was well established, clear water with a PH of about 6.7. I checked nitrate levels and they were high at about 25. I've been doing water changes weekly of about 10% - perhaps not enough. The angel showed signs of a white/greyish slime on its body, was sluggish and not eating, so I bgan treatment with Maracyn. Most were dead within the next day so I moved the remaining three to a hospital tank (white cloud, Red Eye and Orange Glow). I'm continuing the Maracyn treatment and they seem a little better.
As I was draining water from the main tank, I noticed this:

Freaked me out! I didn't see them before and know I would have. Did they appear from beneath the gravel when the fish were removed? Because 80% of the water has been removed? I've been searching on the net to see what these are and the closest description I can find is a Nematode. Honestly, the look exactly like Tubifex work=ms - and I have fed them to my fish - but that was YEARS ago. Would they go under gravel and not appear again until years later?
So, my questions are:
Are these the cause of my fish's death or just a symptom of a dirty tank?
How can I get rid of them? Need I start over by removing and cleaning all the gravel?
What are they?
Sorry for the long-winded post. I hope someone has some thoughts.
Thanks!
